Jailbreak iOS 5 GM (Download Link) with Redsn0w 0.9.9 B3

iPhone Dev Team has just released Redsn0w 0.9.9 b3 to jailbreak iOS 5 GM on all idevices except iPad 2. This new beta version supports iPhone 4, iPhone 3GS, iPod Touch 3G/4G and iPad 1.

Apple seeded iOS 5 GM this morning to developers which can be downloaded from Apple’s Developer Program. There are also reports that iOS 5 GM is actually the public build. However, we suggest to all common users of iDevices to wait just few more days as iOS 5 public build is coming out on October 12th.

As usual Reds0w 0.9.9 b3 provides tethered jailbreak on iOS 5 GM, meaning you have to connect your device with PC, run Redsn0w and select the “Boot Tethered” option after every reboot to put the device into jailbroken state and to bring the cydia apps (some native apps too like Safari) in working condition. Read the following update note from iPhone Dev Team.

Update #11: redsn0w has been updated to 0.9.9b3 to auto-detect iOS5 GM firmware. Remember: it’s still tethered for all devices except for iPhone 3GS with old bootrom. If you don’t use redsn0w to “Just boot” at power up, all jailbreak apps (and even some native ones like MobileSafari) will fail to launch.

If you already jailbroke the GM by pointing an older redsn0w at the beta7 IPSW, there’s no need to re-run the full jailbreak step again…just use this newer one to make the tethered boot easier

All those users who rely on unlock must not update their devices to iOS 5 GM and even to public build. In fact iOS 5 GM will also update the baseband of your device and you might lose the unlock ability permanently or at least for some period until iPhone Dev Team releases a new unlock tool to support iOS 5.

The iOS 5 jailbreak procedure is very simple. Dowload Redns0w 0.9.9b3 and iOS 5 GM on your PC. Run Redns0w 0.9.9b3 and follow the on-screen instructions.
